Is there any way to easily fire both a few Canon 600-EX speed lights and an Elinchrom RX-600. What I am thinking of is a real estate shot with the speed lights inside and the RX-600 providing fake sunlight from outside. I have the Elinchrom remotes for their lights and the Canon STE3. Without buying pocket wizards or similar is there any way to trigger both?
Thanks in advance!
